Struct vtable::VWeakMapped

source · [−]

pub struct VWeakMapped<VTable: VTableMetaDropInPlace + 'static, MappedType: ?Sized> { /* private fields */ }

Expand description

VWeakMapped allows bundling a VWeak with a reference to an object that’s reachable from the object a successfully upgraded VWeak points to. VWeakMapped’s API consists only of the ability to create clones and to attempt upgrading back to a VRcMapped.
